Lugou Bridge is one of the four famous bridges in China. During the Mid-Autumn Festival, we went to Lugou Bridge. The water of Yongding River under Lugou Bridge has dried up, and the live water has been redirected to Xiaoyue Lake. We went near September 18. In the afternoon, standing on the Lugou Bridge, we listened to the alarm to remind the world not to forget our country's shame. Patriotism overflowed. Thousand-mile knife light and shadow are still there, my generation after generation, pointing out the river and mountain is just in time.
